There seems to be a Team DH invasion, and yes, using X items seems to be their whole deal (neat, i guess, but that mostly ends up giving me a free turn. It will probably be really deadly late-game)
fought a few grunts, and fought against DH admin Reginald, an effeminate man (despite that, the sprite seems pretty Lance-like to me) and oh boy this fucker ramped up the difficulty with a Gen 5 Skarmory (it can resist Dark/Ghost moves) + X item usage.
Suffice to say that i lost the fight. My whole team has a pretty bad match up against Steel/Flying types, and the lack of Electric/Fire type moves is really noticeable at this point
